2015 Map of Twelvemile Sink

About this map

Twelvemile Sink sits at the heart of this high-desert terrain in Sweetwater County, where the arid landscape is defined by a series of deep drainages. The area is dominated by the winding path of Twelvemile Canyon, which cuts across the northern and central portions of the sheet, while Buckhorn Canyon and Eighteenmile Canyon define the southern reaches. This modern survey illustrates the sparse human footprint on the land, primarily characterized by the Public Land Survey System grid and remote access routes. Transportation is limited to a few thoroughfares, including the winding Monument Butte Rd and Cr-49, which navigate the elevation changes between the canyon rims and the floor of Lombard Canyon. The map provides a clear look at the intersection of several townships and ranges, showing how modern resource management and land division overlay this prehistoric geomorphology.
